Suggested Edits for the Vertebrae page (Week 1):

• When I initially look at the page, I found that it was unnecessary and distracting that they used the same photo twice. I'd suggest keeping the picture because it clearly labels everything, but make sure it's big enough to read and only have it on the page once.
• There are sections within the page that are not referenced, and if they are they aren't referenced clearly. The page had many links to other pages which I thought was appropriate.
  • No citations/references in the "Regional variation" section (only three at the end)
  • No references in the "Function" section
  • The "Clinical significance" section only has one
  • Only 26 references/citations total
  • The sources that they do have all come from reliable textbooks, dictionaries, or journals that are up to date (arguably the very last reference from 1922 may be out of date)
  • Specifically concerned about citation 20
• The page seemed to stay on topic and was neutral; making no claims on the subject
• I saw no clear indication of any plagiarism or close paraphrasing; they did a well job on using their own words but giving credit to their reference (when they did reference)
• Citations linked and all of the links in the page worked correctly.
• Under "Regional variation", the cervical vertebrae were more represented and discussed in more detail than the preceding vertebrae. Specifically, the sacrum vertebrae has significantly less information on it.
• The development and function sections also hold little information
• Evolution, and significance of this change for the organisms, of the vertebrae is completely left out from the page

Suggested References for Developmental and Evolution Sections (Week 2):

• http://dev.biologists.org/content/142/10/1733
• Question: Should we expand the development section both evolutionary and in general?
  • If so, we'd suggest adding a cross link to the vertebrate wikipedia page where they expand on the evolution of the vertebrate while also adding more references.
    • http://dev.biologists.org/content/142/10/1733

Suggested Edit To Vertebra Page (Week 3):

• The vertebra that make up the vertebral column of the animal allow vertebrates to have more active lifestyles and provides protection of the spinal cord (the dorsal hollow nerve cord), therefore the vertebrae are necessary for almost all vertebrates.

Project Preferences (Week 4):

1. Iguana Page:

• I chose this page because I not only have a high interest in Iguanas after visiting the Bahamas this J-Term, but this page is only at a start state that has a high interest within the lizards and reptile community and this page provides little to no informative information.
  • Sub-topic page: (Talk:Autotomy), Autotomy
  • Sub-topic page: (Talk:Camouflage), Camouflage
  • Sub-topic page: (Talk:Diapsid), Diapsid

2. Microbat page:

• I chose this page because I thought it would be a challenge, ever since I was younger I've had a huge interest in bats, and it is a start page with mid-importance.
  • Sub-topic page: (Talk:Larynx), Larynx
  • Sub-topic page: (Talk:Merkel cell), Merkel cell to do with the wings
  • Sub-topic page: (Talk:Insectivora), Insectivora to do with teeth 3. Garter Snake Page:
• I chose this page not only because it is a start page with mid-importance, but most people come across these snakes but don't have the most helpful resource when they go online to look up what they've just encouGrontered.
  • Sub-topic page: (Talk:Ectotherm), Ectotherm
  • Sub-topic page: (Talk:Moulting), Moulting
  • Sub-topic page: (Talk:Snake skeleton), Snake skeleton

  • I found one good resource to maybe add to the Iguana page.
    • http://www.jstor.org/stable/3881549?seq=1#page_scan_tab_contents
• Dewlap:
  • I worked on finding resources to add to the dewlap page. I focused mostly on reptiles (Iguanas more specifically). I am adding my resources to Hartmacl's sandbox and then we are adding to talk pages. Each of us has picked one specific thing to work on.
    • http://www.sciencedirect.com/science/article/pii/S0166432805800828
      • Talks about the structure of the Dewlap. Also the bio-mechanics of it's movement

Draft 1 of our Article (Week 6):

Game Plan Outline Continued:

Courtney - Iguana/Reptile heart muscles & anatomy

• I'd like to expand on the Reptile page (that I'd add a link to on the Iguana page) or create a section on the Iguana page itself regarding the anatomy/structure of the Iguana heart, specifically going into more detail on the muscles that are involved with the heart.
• All of my sources could provide useful information, but my primary source that seems to be the most helpful is my third reference.
  • Speaks of the reptile heart generally and then is also specific for the Iguana heart, comparing hearts between different lizards, describes function and reason for anatomy and structures, clear/useful pictures, relationship between the anatomy and physiology of the heart, why this anatomy was favored evolutionarily
  • http://vetmed.illinois.edu/mmitch/pdf/reptilecardiology.pdf
• A new source I found discusses more general reptile heart anatomy and function, discussing the muscular ridges that divide the subchambers in the heart
  • http://veterinarycalendar.dvm360.com/reptilian-cardiovascular-anatomy-and-physiology-evaluation-and-monitoring-proceedings

Lexie - Dewlap page

• I would like to add more to the dewlap page about the color of the dewlap and how it forms from cartnoid and pterin pigments. (http://www.sciencedirect.com/science/article/pii/S1096495906002612) There is some information on the coloration of the dewlap on the page, but not much. I would also like to take this subject and talk more about WHY the coloration is the way it is, both of these articles go into all of that.(http://www.jstor.org/stable/1563454?seq=1#page_scan_tab_contents).
• I would also like to add more to the mechanics of the reptile dewlap (http://www.sciencedirect.com/science/article/pii/S0166432805800828), since the dewlap page doesn't seem to discuss the mechanics of reptile's dewlap at all. I would simply give a brief overview of the anatomy/structure, this could connect back to Courtney and Mikayla's articles on the muscles and the skeletal structure.

Mikayla: Iguana page

• Will add a subsection to the Anatomy/Physiology section, focusing on aspects of the skeletal structure. This will also help organize this section as the information present is sparce and scattered.

Bones/Structures I would like to focus on:

• Skull: I would look at anything that would distinguish the iguana from other species of lizards; plus, I would be able to simultaneously research dewlap bone function. http://archeozoo-archeobota.mnhn.fr/IMG/pdf/bochaton_et_al._in_press_iguana.pdf; http://www.jstor.org/stable/pdf/40664967.pdf(plus, the other two resources indicated by me previously).
• Dewlap: It is thought that the hyoid bone/skeleton is the mechanism behind dewlap extension in the Anolis equestris, a lizard in the same family as the green iguana. https://eurekamag.com/pdf.php?pdf=007364568

I think that focusing on these aspects of the skeletal system will relate very well to the work of my teammates as well: Courtney would be able to provide input regarding the muscles surrounding the dewlap/its function and Lexie and I could collaborate on how to simultaneously examine the dewlap from different angles (Me skeletal structure, her more of the mechanism/function).

Finally, I would like to compile the above information in an integrative, yet concise manner. My teammates will also provide valuable information regarding my topic.

Peer Review

Hi Courtney, it seems like you have a clear direction you'd like to take your studies. I think your information regarding why the iguana heart is different from other reptilian hearts could prove to be very interesting and a good addition to the Wikipedia knowledge base.

Hi Lexie, from the information given it sounds like an addition regarding the mechanics of the dewlap would be very useful to your specific Wikipedia page. I am not sure if there is a pigmentation page already in existence, but if there is, maybe just a simple link to the page within the Dewlap Wikipedia page would help explain the general reason why pigmentation occurs the way it does.

Hi Mikayla, it seems like you have more information regarding the skeletal system of the iguana's dewlap than the skull at this point in time. Maybe it would be beneficial to focus your researching efforts on that particular subject in order to write a more comprehensive addition to the Wikipedia page--rather that dividing your efforts. That said, it would be incredibly interesting to see how the skull may differentiate, and definitely something to keep an eye on as your dissection proceeds.

Response to Peer Reviews (Week 7):

Mikayla

Group: I think that we should work more on organizing our section/integration so that we have a specific direction and plan for each person. This is especially important when it comes to the dewlap because Lexie and I will be working together. I want to make sure that Lexie and I have our own directions. As mentioned by several peers, it will be important to establish a formal citation list in the sandbox.

• FigginsRD/Cksmith8/Newmansr/Murray4329/Beckjt: I agree with the addition of pictures to my section and will be implementing this using dissection pictures from our group. Our group will also discuss how to integrate our sections with each other - as many of you have mentioned, it will be important to work together with each other in order to establish good article contributions (for each of us).

• Hobbscassidy/Julisymmons: I will be using the skulls of other lizards sparingly in order to draw more attention to the iguana skull. I will use the skulls of other reptiles as needed to highlight the unique aspects of the iguana skull (potentially teeth). I will work to narrow my focus to important aspects of the skeletal structure such as hyoid bone for dewlap and potentially teeth as they relate to diet.

• Terhaaed: I am narrowing my focus by looking at specific bones that make the iguana unique from other reptiles. I will collaborate with my other group members to lessen the workload involved with this.

• Grant Kido: I will work on continuing to complement Lexie's section with my findings and will use my sources as needed to illustrate variations in the dewlap/other unique anatomical structures.

• Megamanhuy: I am glad that you are in agreement with starting the new subsection about skeletal structure! I will also implement a reference list on the shared sandbox page.

• Ahyneman: Several other peers have mentioned organization. I will work on this by drafting a more specific outline in the future, once I begin editing my draft once more and collaborate more with my group mates. .

• Professor Schutz: I plan to fix my sources so that they are in Wikipedia format. I would love to see the cast of the skull! I think that this will be much easier than excising the skull from our iguana. I would also like to see how the group last year dissected their iguana. I will like to use teeth as one aspect to focus on skeletally - I think that this will help with diet and would be cool to look at since the iguana is an herbivore.

Ayersmm (talk) 23:39, 2 April 2017 (UTC)

Courtney

Group: I'd agree that we should get more specific with areas within each of our topics we want to add. I'd also be beneficial to site all of our sources and have them compiled in the sandbox so it's a little more organized and makes it easier for our final draft.

• FigginsRD: I think my first source will help me compare the Iguana heart to other reptile hearts, but I'm starting to narrow down on what I want to focus on and I think it's important to focus on getting the information out there on the Iguana heart anatomy because there isn't anything on the page or the reptile page.

• Cksmith8: I think it's a good idea to add this to the Reptile page and add a link to the Iguana page. The reptile page is more widely used and there are many similarities with the iguana heart that relate to all reptiles.

• Newmansr/Megamanhuy: Like I said above, I like this suggestion to actually compile the cited list of our references to help with our organization and clarity moving forward with our edits.

• Benson02: I thought when I looked at the reptile page it had a good start with the circulation, but that it needed more on the structure, anatomy, and function. I'm glad you agree with me there, I think that's where I'm going to focus in on!

• Grant Kido: I'd love to add a picture and I've already been trying to find old sources that I could use. But I think my best bet would be to try and get a good picture during my dissection. I'll have to be very precise with the cross-section though because it is a juvenile Iguana it may be difficult.

• Julisymmons: I have found differences between the Iguana's heart and other reptile hearts, but I'm not sure yet with how significant they are, so I think this will lead me in the direction to stay more general and link to the Iguana page. I plan to do some more digging though, it would be nice to add a complete section to the Iguana page.

• Beckjt: It's a good suggestion to add a taxa, but I think I'd rather focus on getting the information about the anatomy and function of the heart muscles than go into the evolution of the heart. I think it would be taking on too much if I tried to tackle both.

• Terhaaed: I'd agree with you that our first draft is very broad and we might be tackling too much. After looking at these peer reviews, I think I'm going to narrow down my topic to specifically addressing the Iguana heart anatomy; this seems like the best starting place for the page.

• Professor Schutz: I would love to be able to add images to the page, I think that was the initial drawback to the page that I saw when I first read it and I think it helps readers to better understand when they have a visual to follow along with the information given. Using my textbook can help me narrow down on the important/significant differences as well.

Hartmacl (talk) 03:51, 3 April 2017 (UTC)

Lexie

Group: I do agree with most of the comments, that we need to be more specific about what exactly we want to add to what pages. I do also think we need to make sure to cite sources and work on that. Also, I do think it's a good idea to discuss and show what differences me and Mikayla are looking at in the dewlap sense our ideas somewhat overlap.

FigginsRD/Cksmith8/ Newmansr/Grant Kido/Benson02:: Thank you for your feedback and comments, I agree with all of the comments you have posted. I also believe that I should work on adding more about the evolution of the Dewlap and why it exists. I also plan to look more into why reptiles, like the Iguana, use their dewlap, what is it for specifically? Mating? Communication? Thank you!

Hobbscassidy/Julisymmons/Beckjt/Megamanhuy/Ahyneman: Before looking at your comments, I didn't really realize how much I had left out about the actual anatomy of the dewlap! I definitely plan to put in a section about the anatomy and structure and how the dewlap functions. Also, I like the suggestion of adding in images, I hadn't really considered this. If I can find sufficient images I will add one in. Thank you for these comments!

Terhaaed/Murray4329//Hansonsl: Hello all, thank you for your comments! I had noticed from all of your comments that there were a lot of structural issues in our draft and citation problems. As a group we've looked at thus and are beginning to fix it and restructure our draft, so thank you! I also hadn't thought to look for a pigmentation page, but this would be helpful to simply link on the dewlap page, if the information is already out there. Thank you!

Professor Schutz: Thank you for your feedback, I have started looking at pages I could link information to and have found a couple possible pages. This way I can simply link a page about pigmentation, for example, instead of writing more information about it on the dewlap page. I also hadn't thought about thermoregulation at all with the dewlap yet, but I do plan to look into this more now that you've brought it to my attention. I am also planning to look more into the why for the dewlap involving sexual display. Thank you!

Draft #2 (Week 8):

Courtney

An Iguana heart, like the majority of the chelonian hearts, is composed of three chambers with two aorta and one ventricle, cardiac involuntary muscles. The main structures of the heart are the sinus venosus, the pacemaker, the left atrium, the right atruim, the atrioventriular valve, the cavum venosum, cavum arteriosum, the cavum pulmonale, the muscular ridge, the ventrical ridge, pulmanary veins, and paired aortic arches.

I'd like to link the pages of each of these structures and add more to circulation of the blood through the heart.

*Add pictures of the Iguana heart bisected under the microscope, labeled correctly.

Lexie

The anole species has been found to have enhanced vision for color and depth perception. This species is able to see dewlap coloration from a far distance, giving the dewlap use and importance. Males will display their dewlap to attract females. Studies have found that the pigments generating this color are pterins and carotenoids.

The dewlap is extended and contracted. The muscles creating this movement are the ceratohyoid muscles connected to the hyoid apparatus. The neurons directing this movement are the motoneurons found on one side of the throat and larynx.

Mikayla Article Outline/Draft

Page: Iguana

Section: Anatomy and Physiology

(NEW) Sub-section: Skull Morphology and Diet

• Diet

Iguanas feed exclusively on vegetation and foliage, making them herbivores. In order to aquire, process, and digest plant matter herbivorous lizards have higher bite forces relative to their size than carnivores or omnivores.

(Including an image of an iguna eating would be helpful to see how they chew/what they eat)

• Skull

Herbivorous lizards have been found to have taller and wider skulls, shorter snouts, and larger bodies relative to carnivores and omnivores. These skull modifications result in a strong bite force and efficient processing of plant matter.

(I will include dissection pictures of our iguana, with appropriate measurements, in order to detail this. I will also look at the skulls of other carnivorous or omnivorous lizards in order to show the differences)

• Teeth

The iguana has teeth adapted to an exclusive herbivorous diet. The teeth are attached to the surface of the jaw (acrodontal) and project upwards. The teeth themselves are small with serrated edges for gripping and shearing food.

- Picture will be included from our own dissection and online, if needed-

Going Live (Week 9):

For example, Iguana hearts, like the majority of the squamates hearts, are composed of three chambers with two aorta and one ventricle, cardiac involuntary muscles. The main structures of the heart are the sinus venosus, the pacemaker, the left atrium, the right atruim, the atrioventriular valve, the cavum venosum, cavum arteriosum, the cavum pulmonale, the muscular ridge, the ventrical ridge, pulmanary veins, and paired aortic arches.

There is little information about the anatomy of reptile hearts here, therefore adding the Iguana heart for an example will help people understand the circulation of the heart as well as the anatomy.

Lexie:

-added more about the coloration of dewlap, movement, and citations.

Mikayla:

Added skull morphology/diet section.

Included hyperlinks/citations as necessary. Expanded on the idea of the biomechanics of the iguana skull. Explained acrodontal. When I have extra free time I will look at the skull of the iguana available (as well as the iguana from 2016) and see if I can find an image of teeth to compare to the illustrations on Wikipedia. I also saw that one of the scientific papers I found discusses the akinetic skull of uromastyx and iguana (both herbivores). I will look into that a little more before we finalize the wikipedia add-on. Finalized product will have actual cadaver images.

-Continued searching for images after 11pm to see what other images may come in use; that is why some images are added after 11pm-

Continue Illustrating Article (Week 11):

I've tried uploading the photo of the bisected Iguana heart I'd like to upload to the lizard page, but I'm having technical difficulties uploading it even to my sandbox.

I've added the bisected Iguana heart image to the lizard page, now I want to finalize all my edits by linking the lizard page and iguana pages together in an appropriate and convenient way for users to follow.
